This invention relates to draft, dust weather -excluders (hereinafterfor `brevity acts asa fulcrum, by means provi ed on the hinged member.

According lto this invention the means onthe hinged member formoving thedraftexcluding memberinto its Operative position is mounted on the freeed e of the hinged member instead of on Vthe ingededge. In this way the`draft-excluding member is lowered into its inoperative positionimmediately thehinged member begins to open and y is moreover not raisedinto 1ts operative position untilthe hinged member is nearly` shut,which is particularly useful in its application to hinged members `wherethe draft-excluding membermi htbe otherwise damaged by being subjectetolpressureby a moving object or a personsfoot,when 1n its raised orpartially raisedposition. The

said means comprises a member so shaped as 80 to engage under andgradually lift or lower the draft-excluding member as the hinged membercloses or opens respectively. two opposite edges of the said member maybe both shaped in the manner specified so4 that it lcan be applied toeither right hand or left hand hinged members.

In addition, a flat member` adapted to be secured to the front of thehinged member and to project along the whole length` thereof is rovided,this member extending downward y so as to overhang the dravft-exclud ingmember when the latter isin its operative position. This serves toprevent any rain or draft from passing behind the top of thedraft-excluding member.

Referring to the drawings V:V

Fig. 1 is a front view of aportion of the hinged member showing theexcluder applied thereto. l

Fig. 2 is a section on line II-II inFigrl.

Fig. 3 is a fragmental plan view.

In the constructionillustrated `the draftexcluding member 1 consists ofalong, .flat metallic strip, which is folded over upon itself (see Fig.2). Near its extremity, the

upperY foldedfover portion of said member"` i (.consldered when thelatter is in its inoperal tiveor substantially horizontal posltion vshownin dotted lines" in Fig. 2) is curve ,y j outward at 1a away fromthe bottom portion yo0. y

lb of the member. This may be formed b l rolling the strip to therequlred section.

,long metallic strip, or plate 2, (hereinafter -called sill plate) issecured on the top of thesill of the hinged member, partly at theoutsideand partly below the latter, said sill plate being formed withupwardly projecting flanges 2a and 2b, the said sill plate being` ofchannel shape. j

he draft-excluding member is loosely ar- 7o ranged in the sill platebetween the flanges l thereof, the edge of the lower `folded-overportion lb of said member bearing lagainst y the inside of the outermostflange 2b on the sill plate `and the curved part of the upper `I5` i ifolded-over portion l* of said member extending around the, edge oftheoutermost flangeon the sill plate. The curvature of the part l issuch that italwa s maintains contact Withthe edge of the ange 2b and B0when in its horizontal position, shown in dotted lines, it is just flushwith the front` of this sill plate. The edges of the draftexcludingmember act as a loose hinge therefor. r Il y The member (hereinafterreferred to as operating late) provided `on the hinged member 4 or movmgthe draft-excluding member into its operative position comprises asubstantially rectangular plate 5` having o0 apertures for screws 6 `bywhich it is secured on the ed e of the hin ed member. This operating pate is provide at its lower front edge with anfinwardl curved recess 5aso shaped as to provide a s arp projection o5 5* at the lower corner ofthe operating plate. l Preferably this operating plate is provided withsuch recesses on oplposite edges thereof (as shown in Fig. 2) so t at itcan be applied to left or right hand hinged members. The lower part ofthe hingedmember is preferably cut away so that the plate is mounted ina counter-sunk position` thereon and in a position in which it extendsbelow the hinged member. hinged member (hereinafter called a fbergeplate) is flat and is also fixed by screws 9 to the front of the hingedmember and extends across the whole width thereof."-

In order toA allow the Operating member to 11e The front plate 8 on thelos all' be raised into its operative position when the hinged member isnearly closed and lowered into its inoperative position immediately thehinged member beings to open, the

i frontlower edge of the hingedmember must be cut away on a curve asindicated at 7,

VFigs. l and 2, for the whole width thereof.

The berge plate 8 is adapted toextend below the cut away portion of thehinged member so as to screen it and also to overhang `thedraft-excluding member when the latter is in its operativek position.

The operating plate on the hinged member is as previously stated locatedupon the free vertical edge thereof and projects downwardly belowthehinged member, the sill plate and/or the sill being slotted or cutaway at l() so as to provide a passage Jfor the operating plate. h I

When the hinged' member 1s being closed, the operating plate thereoncontacts with the innermost longitudinal edge of the draft-ex- Y cludingmember, turning the latter upward about the longitudinal edge of thevbottom folded-over portion of said draft-excluding member, said edgebearing against and hinging on the outermost flange oi' the sill member.When the hinged member is fully closed, the draft-excluding member isinclined' thereto, and thus covers the aperture between the bottom ofthe hinged member and the top ot the sill.' Moreover, when saiddraft-excluding member is being turned upward, the outwardly projectingpart of the upper folded-over portion Vthereoil moves around theadjacent flange of the sill member, its inner tace contacting with thetop of said flange when the draft-excluding member is in its fullyinclined, or operative, position. baclr ot the draft-excluding member,drafts, dust and rain have first to pass the additional draft-excludingmeansA formed by the contacting ilange and the curved part on the upperfolded-over portion of the draft-ex? cluding member. lt will be obviousthat the said curvedV part effectively screens the loose joint betweenthe ulcrumed edge of the portion 1b and the sill.

In addition, as the berge plate overhangs the upper edge of theexcluding member, this will prevent drafts, dust and rain from passingbetween the upper edge of the draftexcluding member and the hingedmember and thereby serves as supplementary draftexcluding means.

ln a vmodied construction, the silll member is made from a flat,metallic strip which is folded back upon itself to form the spaced,

:upstanding flanges at the outermost longitudinal edge of the member.Two additional drait-excluding means are thus provided by thisconstruction; one being formed by the contact of the inner face of saidoutwardly and forwardly projecting part onthe rlhus, in order topenetrate to the draft-excluding member With the innermost flange of themember on the sill, and the other by the Contact o the longitudinal edgeof said outwardly and-,forwardly projecting part and the, inner tace otthe outermost flange of the member on the sill.

My improved weather-excludingdevice is particularly easy to manufactureand fit. The member can be secured to 'any existing door sill by a fewscrewsand it is then only Ynecessary to arrange-theV draft-excludingmember loosely in said member. The devicev is also very elhcient inaction, owing to the 'Y provision thereby of one, or more supplementarydraft-excluding meansas described;-
